* MAN, or BOSTON, MASSACHUSETTS.

` Letters Patent No. 85,908, dated .Tenue/ry 19, 1869.

The Schedule referred to in thse Lettere Patent and making part of the same.

To all 'whom it 'ma/y concern Be it known that we, LUCTUS OOLBY, of Morrissville,

county of Lamoille, State of Vermont, and JOHN D. GILMAN, of Boston, county of Suffolk, State of Massachusetts, have invented an Improved Oarpet-Stretcher,

Tack-Driver, and Tack-Puller Combined; and 'we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which v Figure 1 represents a perspective view of our invention complete.

The Aobject of our invention is to produce a carpet stretcher, tack-driver, and tack-puller combined, which shall be at once convenient for use, cheap, and durable.

Our invention consists in having the hammer, stretcher, and puller in two pieces or arms, with a spring, the hammer operating'over the stretcher.

In-the ldrawings- A is a suitable-sized plate, of metal, provided with teeth h and slot p. This plate and teeth form the stretcher-part of our invention.

B is a shank to plate A.

To this shank is attached handle H.

K is abar attached to B at l by means of arm E and pin t. This bar K works parallel toB.

' At one endof K, over plate A, is attached hammerhead O.

A spring, S, is-attached to shank B at m,"and bears upon arm K at b.

'At the front of plate A is cut slot p.

Shoulder a, on one end of hammer-head C, plays Within slot p.

To one side of plate'A is attached claw L for drawing tacks.

^ The operation of our invention is as follows:

A tack is easily and conveniently pickedup by end f ofthe hammer C, by the hammer being magnetized for this purpose. The tack can then be inserted, bya

slight blow, into the edge of a carpet, and the instrument turned over, then stretching the carpet as desired by plate A and teeth h, taking care to have the tack come within slot p, and of course the tack is then directly under hammer C. Now, while the hand holds H, and the carpet is vbeing crowded to its place, the 'end of bar K is pressed down by pressure at D, and `the pressure vbeing suddenly Withdrawn, the strength of sprin g S causes hammer O to come'down with sufficient force upon the tack to drive it home; or partly, as the blows can be repeated till the tack is driven :homey Or, the tack can be easily handled with `the disen' gaged hand of the operator, and conveniently attached to the hammer by this disengaged hand, and the tack is heldto the lower face of the hammer by magnetic force, and when thel carpet is in the right place, the other hand lifts the hammer, by pressure at D with the thumb, and withdrawing the pressure, the action of the spring S drives the tack home.

This combination has another advantage, that of liaving a claw, L, ready to draw a tack, if desired.

We are aware that combined carpet-stretchers and tackdrivers hav'e been made and used, but not constructed as we construct this@ We are not aware of any combined carpet-stretcher, tack-driver, and tack p nller.

. We disclaim the hammer operated by a combination of levers, and disclaim. thearm when an additional hammer` detached from the stretcheris required; but

The combination cf plate arranged as a puller and stretcher, with the arm K pivoted at t', and furnished with the hammer O at one end, and held he thy spring S at the other, substantially as and for the purposes set forth.

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.

LUOIU S OOLBY. JOHN D. GILMAN.
